Video playback and thumbnails issues for videos #39

Closed sheilabrennan closed 10 years ago

@kimisgold can you help us to figure out what is happening?

This is an example of an mp4, that has no thumb in the public theme, that also doesn't play in the browser. http://dev.omeka.org/mallhistory/items/show/262

But, the file is viewable and plays in dev.omeka.org/admin/files/show/331

I've run image derivative plugin again on video files and that doesn't seem to correct the problem.

Any idea what might be happening?

If a video doesn't have a thumb, it's because the Imagemagick install on the staging server can't create derivative images from the video files.

The video is viewable and plays in Firefox for me both on admin and public side. I'm having trouble with my Quicktime plugin for Chrome, but looking into that now.

John just took a closer look at the videos, and he says the current encoding for the videos (MPEG-4, not to be confused with its MP4 container) is older and not well-suited for web playback. He recommends they be re-encoded to H.264 codec.

Thanks very much for investigating this. We'll see what we can do with the file we have.
